Any help would be greatly apprecieated. Here's an extract from traceroute.c: /* * traceroute host - trace the route ip packets follow going to "host". * * Attempt to trace the route an ip packet would follow to some * internet host. We find out intermediate hops by launching probe * packets with a small ttl (time to live) then listening for an * icmp "time exceeded" reply from a gateway. We start our probes * with a ttl of one and increase by one until we get an icmp "port * unreachable" (which means we got to "host") or hit a max (which * defaults to 30 hops & can be changed with the -m flag). Three * probes (change with -q flag) are sent at each ttl setting and a * line is printed showing the ttl, address of the gateway and * round trip time of each probe. If the probe answers come from * different gateways, the address of each responding system will * be printed. If there is no response within a 5 sec. timeout * interval (changed with the -w flag), a "*" is printed for that * probe. * -- Harley Privitera "No matter what you do, one of our Digital Equipment Corp. planes will get thru to the target." harley@gotit.shr.dec.com "What is the target?" ...!decwrl!gotit.shr!harley "Moscow."
